  • Patent number: 7240801
    Abstract: A screening panel 10 comprises a peripheral frame 12 consisting of a pair of mutually laterally spaced side members 14, 16, which are integral with a pair of mutually axially spaced end members 18, 20. The side members 14, 16 and end members 18, 20 define corners of the panel 22.1, 22.2, 22.3 and 22.4 and the peripheral frame 12 where they meet. A plurality of mutually spaced ribs 15 extend across the periphery of the panel 10 to define a screening surface. The side members and end members are rectangular in cross-section, thereby defining substantially flat upper peripheral surfaces 12.1, outer peripheral surface 12.2 and lower peripheral surface 12.3 of the peripheral frame 12 and thus also the panel 10. The panel 10 includes locating recesses 24 provided at or near to the corners 22.1, 22.2, 22.3 and 22.4 of the panel 10. The panel 10 also has separate securing recesses in the form of semi-circular grooves 30 formed in the lower surface 12.

  • Patent number: 5938042
    Abstract: A screening arrangement support frame component in which a pair of complementary elongate component members have body portions and cavity defining formations. The component members are secured side by side to one another such that the body portions abut and the cavity defining formations register to form a plurality of cavities for receiving socket elements. A plurality of socket elements, each defining a socket for receiving a protrusion that secures a screening panel to the component, the socket elements being mounted in the cavities when the component members are secured to one another. The thickness of each support frame component at the locations where the body portions abut is smaller than the cross-sectional dimension of the socket elements mounted in the cavities.

  • Patent number: 5713986
    Abstract: The present invention provides a method of forming a desired pattern with a coating on a substrate. The method includes the steps of applying a water soluble resist material in a predetermined pattern to a surface of a substrate, drying the resist material, depositing a coating on the surface of the substrate to form a coated substrate, wherein a portion of the coating overlays the resist material, and dissolving the resist material on the coated substrate with water to remove the resist material and corresponding overlaying coating and form a desired coating pattern on the substrate surface. The dissolving step preferably includes the step of directing high temperature and high pressure water sprays at the surface of the coated substrate to wash off the resist and corresponding overlaying coating. The removal of the resist material may include a prewash operation wherein the surface of the substrate is wetted with water and coating is allowed to soak.

  • Patent number: 5707412
    Abstract: The present invention discloses a method of reducing marking of a heat softened glass sheet which results when portions of the sheet are contacted by glass sheet handling equipment. The portions of the sheet susceptible to marking are sprayed with an inert material having a melting point and decomposition temperature of at least 1200.degree. F. to form a layer that protects the sheet portion against marking from the equipment. In one particular embodiment of the invention, the lower major surface of a glass sheet is sprayed with an aqueous solution of sodium sulfate to form a layer of sodium sulfate along the glass surface which protect against marking of the glass by conveyor rolls.

  • Patent number: 5664685
    Abstract: A screen support frame component is provided. The screen support frame component supports modular screening panels which are of a hard wearing synthetic plastics material such as polyurethane and are removably secured to the screen support frame component. Each of the screen support frame components includes a base which is elongate plate having a planar surface. A plurality of lugs are longitudinally spaced along the length of the base and project laterally on both sides of the base so that the planar surface of the base extends onto the laterally projecting lugs. A plurality of tubular spacer elements are provided on the base and on the lugs to project upwardly from the planar surface. Each tubular spacer element has a tubular side wall and one open axial end. It further has an annular shoulder inwardly of the open end, and a sloping face flaring outwardly towards the open end. The annular shoulder constitutes a securing formation for securing the screening panels to the screen support frame.

  • Patent number: 5641576
    Abstract: An organic acid anti-staining composition for glass sheets is disclosed herein whereby the corrosive effects of very low pH are eliminated by buffering the organic acid. The buffered organic acid has a less acidic pH, but is as effective as unbuffered organic acid in neutralizing alkali formed by sodium from the glass to prevent staining of the glass surface.
